Abstract (en)
[origin: US2004059059A1] A process is disclosed for producing silicone copolymers, wherein the process comprises the steps of: (a) providing at least one multi-stage blade-mixed plug flow reactor having an entry and an exit; (b) continuously feeding (i) hydrogen siloxane, (ii) olefinically substituted polyether or olefin capable of reacting with said hydrogen siloxane, and (iii) catalyst for the reaction to the entry of the multi-stage blade-mixed plug flow reactor, and (c) continuously withdrawing from the exit of the multi-stage blade-mixed plug flow reactor a stream that comprises silicone copolymer and is substantially free of unreacted hydrogen siloxane, provided that said hydrogen siloxane and said polyether or olefin have a residence time at reaction temperature in the multi-stage blade-mixed plug flow reactor sufficient to effect substantially complete hydrosilation
